Ultisols, commonly known as red clay soils, are one of twelve soil orders in the United States Department of Agriculture soil taxonomy. Red clay is used for its beauty benefits since the dawn of time, this natural mineral owes its colour to a high concentration of iron oxide. Naturally rich in trace elements, it stimulates microcirculation in the blood vessels to really wake up the skin. Red clay is suitable for everyone, and those with skin that is sensitive, irritated, tired or prone to couperose or redness will find it especially appealing.
